Through model verification and algorithm correction, many factors unfavorable to environmental protection existing in the production of export products abroad are analyzed. The growth trend of export trade volume of industrial industries and regions with a high degree of openness is generally consistent with the emission trend of environmental pollutants. Environmental pollution restricts China's economic growth and brings certain negative effects on China's economic growth, The relevant data analysis suggestions for improving the impact of export product production on environmental pollution are put forward.

Due to their unique properties, perfluorinated substances (PFAS) are widely used in multiple industrial and commercial applications, but they are toxic for animals, humans included. This review presents some available data on the PFAS environmental distribution in the world, and in particular in Europe and in Veneto region of Italy, where it has become a serious problem for human health. The consumption of contaminated food and drinking water is considered one of the major source of exposure for humans. Worldwide epidemiological studies report the negative effects that PFAS have on human health, due to environmental pollution, including infertility, steroid hormone perturbation, thyroid, liver and kidney disorders and metabolic disfunctions. In vitro and in vivo researches correlated PFAS exposure to oxidative stress effects (in mammals as well as in other vertebrates of human interest), produced by a PFAS-induced increase of reactive oxygen species formation. The cellular antioxidant defense system is activated by PFAS, but it is only partially able to avoid the oxidative damage to biomolecules.

This study aims to estimate the negative effects of COVID-19 on the Jordanian economy. These effects are expected to coincide with the results of studies carried out by international institutions. For example, the International Labor Organization (ILO) estimated indicate an increase in the number of unemployed to 5.3 million (the “low” scenario) and 24.7 million (the “high” scenario), from a baseline of 188 million in 2019 (ILO, 2020a). Experts from the World Bank and the International Monetary Fund (IMF) confirmed that the global economic downturn (caused by the coronavirus pandemic) is the largest in the past eight decades, which will lead to an increase in poverty and inequality and harm economic growth in the long term. (News 18, 2020). To measure the impact of COVID-19 on the Jordanian economy, the following indicators were adopted: an economic growth, an unemployment rate, a foreign trade (imports and exports), public revenues, public spending, a public debt, and a budget deficit. The study relied on data contained in reports issued by international institutions and official institutions in Jordan. The results indicate a slowdown in the rate of economic growth, an increase in the unemployment rate, a decrease in exports and imports, an increase in the public debt and the budget deficit

Purpose This paper aims to examine the impact of interest rate liberalization on economic growth and the relevance of corruption in the five selected sub-Saharan African countries. Design/methodology/approach The study used the modified version of Driscoll and Kraay’s model by Hoechle, which solved the effects of cross-sectional dependence and heteroscedasticity. Findings The findings reveal a positive impact of the index on economic growth, and it was found that foreign direct investment (FDI) and credit to private sector by banks (CPSB) all stimulate economic growth. The interaction terms of corruption with FDI and CPSB indicate negative effects that show how corruption erodes the benefits of liberalization. Finally, the paper recommends the pursuit of appropriate policies with the sole aim of eradicating corruption and providing a conducive environment for business. Originality/value The paper developed a composite domestic financial liberalization index to capture the timing and essential dimensions of the reform process. The study investigates the effect of interest rate liberalization on economic growth and the relevance of corruption. Most of the recent and past studies only examined the impact of interest rate reforms on growth without investigating the relevance of corruption.

China’s “industrial restructuring” has expanded the proportion of the tertiary industry in the economy and promoted the development of local tourism. The ongoing “industrial structure upgrading” is intended to make the industry bigger and stronger, which will promote the growth of local tourism. As a tourist resort, nature reserves have been attracting a large number of tourists and have great development potential and economic value. Under this situation, various management agencies of nature reserves have successively carried out tourism activities and carried out tourism development and construction. However, there is no doubt that both tourism activities and development will have an impact on the ecological system of nature reserves. The existing legal system of nature reserves in China emphasizes the prohibition of behaviors that directly destroy the ecological environment and ignores the impact of human tourism activities. The continuous increase in the number of tourism in our country, brought on nature reserves of rich tourist income at the same time, a large number of facts show that tourism has become a source of environmental pollution, so it is necessary for tourism environmental pollution the main way to do a summary and its particularity, summing up the basic law of tourism affect the environment, thus provide the basis for strengthening the environmental protection from the point of view of tourism management. The emergence and development of tourism culture is inseparable from the influence of the environment, and tourism culture also affects the environment. The negative effects and negative effects of tourism culture development on the environment are becoming more and more evident, which has aroused people’s general concern. In recent years, the negative impact of tourism and cultural activities on the environment has been paid much attention to by many scholars at home and abroad. This paper discusses the impact of tourism activities on nature reserves, and discusses the causes of this problem, so as to analyze the strategies to ensure the harmony and order of nature reserves in tourism activities.

The work is devoted to testing the hypothesis of the existence of an inverted U-shaped dependence of economic growth on the level of environmental pollution, which was based on the concept of the ecological curve of Kuznets. The authors, using econometric methods and data from the World Bank, show that the hypothesis is correct: there is a turning point between the positive and negative nature of the dependence of economic growth on the level of CO2 emissions. The hypothesis is confirmed for low- and middle-income countries, and the dependence is linear negative for countries with a high level of income. Based on the results, the authors formulate recommendations on environmental regulation in accordance with the level of the country's economic development.

Subject. China's industrial sectors are important vehicles that made China the global leader of GDP and economic growth. However, China managed to reach such results sacrificing its environment. The study discusses the coordination of actions spurring the economic growth and environmental protection in order to avoid such sacrifices for the sake of the national economic development. Objectives. We examine the mechanism of bilateral effects on the economic growth of China's industries and environmental protection to provide the empirical framework for the reasonable natural protection policy and environmental regulations. Methods. Theoretical projections stem from the analysis of economic literature and empirical research on resources, environment and sustainable economic development in the existing theories of economic growth. Results. Having analyzed how the environmental pollution and the industrial economic growth of China correlated, we found that a set of various environmental pollution indicators strongly differed from the empirical findings of the study. Therefore, it is still not found how the economic growth of China influenced the environmental pollution. Conclusions and Relevance. The improvement of the environmental quality is not an unavoidable endogenous result of the economic growth. If the Chinese industrial sectors continues growing extensively, the environment will grow even more polluted. It is necessary to determine a reasonable environmental protection policy to combine it with economic growth, and tighten the environmental regulations.

Environmental pollutants can exert sublethal deleterious effects on animals. These include disruption of cognitive functions underlying crucial behaviours. While agrochemicals have been identified as a major threat to pollinators, metal pollutants, which are often found in complex mixtures, have so far been overlooked. Here we assessed the impact of acute exposure to field-realistic concentrations of three common metal pollutants, lead, copper, arsenic, and their combinations, on honey bee appetitive learning and memory. All treatments involving single metals slowed down learning and disrupted memory retrieval at 24 h. Combinations of these metals had additive negative effects on both processes, suggesting common pathways of toxicity. Our results highlight the need to further assess the risks of metal pollution on invertebrates.

Background: Cytological samples are cleared with xylene in two or three baths during a Pap test, however, this solvent has a high degree of toxicity, and being a controlled reagent infers high costs for its purchase and implications for environmental pollution. We estimated the impact of xylene during the Pap test in terms of the number of liters and cost of two baths of xylene, and also estimated the impact with three baths  Methods: This cross-sectional study was carried out in four hospitals of EsSalud in Peru in two stages. First, the analysis of the impact due to the use of two baths of xylene was conducted during the period 2015–2019, and second, the estimates were calculated based on the assumption of three baths of xylene for the years 2020–2025. The assumption was based on the recommendations of the 2018 EsSalud cytology guideline. The monthly amount of xylene was ~10 liters per bath/month and the cost per liter was estimated at 8.13 USD (27 soles).  Results: For the staining of 594,898 cytology tests, 7,848 liters of xylene were necessary, resulting in a cost of 60,861 USD (202,068 soles) during the period 2015–2019. The estimates showed a maximum assumption of 9,483 liters and 77,110 USD (256,040 soles) for the use of three baths of xylene in the four EsSalud hospitals (p = 0.0025) during the period 2020–2025.   Conclusions: We determined that there was a high economic impact of using xylene with two baths from 2015 to 2019 and a dramatic increase in costs with the possible use of three baths of xylene in the Pap test for the following five years.

This article focuses on the interaction between China's industrial agglomeration, foreign direct investment (FDI) and environmental pollution of public health in the past 15 years. By conducting theoretical and empirical research, we try to reveal the relationship and mechanism between the economic growth and public health from the perspective of environmental pollution. By constructing an embedded theoretical model of industrial agglomeration and FDI, this article combines other environmental pollution influencing factors, expounds the impact mechanism of industrial agglomeration on environmental pollution. Based on the provincial-level panel data of China on environmental pollution and industrial agglomeration, the empirical test is carried out through the threshold panel regression model. According to the results, industrial agglomeration can significantly rectify the regional environmental pollution, thereby benefiting public health. FDI has a phased impact on the relationship between industrial agglomeration and environmental pollution. Specifically, when the level of FDI is low, the positive improvement effect of industrial agglomeration on environmental pollution is relatively strong. This is mainly because industrial agglomeration can promote economic growth, technological progress, and enhance environmental awareness. When the level of FDI exceeds the first threshold and continues to rise, the positive improvement effect of industrial agglomeration is maximized. Before the level of FDI exceeds the second threshold, this effect gradually weakens. The population concentration and excessive expansion of city scale brought about by industrial agglomeration will lead to the increase of regional resource and energy consumption, thus aggravating environmental pollution. The policy implication is that while the government and enterprises are vigorously increasing the level of foreign investment, they must pay equal attention to economic growth and public health, and the level of industrial agglomeration should match the level of foreign investment so as to give full play to the positive improvement effect of industrial agglomeration on environmental pollution, and realize the coordinated development of the regional economy, environment and population health.
