: The increase of crop production along with stricter requirements on food security have augmented the demand of new and eco-friendly bactericides. Most of the bactericides used at the moment consist of persistent organic substances, representing a risk for environmental and human health. For instance, agriculture bactericides used for crop protection includes copper-based, dithiocarbamate and amide bactericides, which are not biodegradable, resulting in the necessity of further research about the production of new active principles that attack microorganisms without producing any harmful effect on human health or environment. The biosurfactant extract evaluated in this work as a bactericide, is obtained from corn steep water, a residual stream of corn wet milling industry, which is fermented spontaneously by probiotic lactic acid bacteria that possess the capacity to produce biosurfactants. In previous works, it has been demonstrated that this biosurfactant extract is able to promote the growth of Lactobacillus casei in drinkable yogurts, though its antimicrobial activity against pathogenic strains has not been evaluated at the moment. The results obtained in this work have proved that this biosurfactant extract is effective as bactericide against Pseudomonas aeruginosa and Escherichia coli, at concentrations of 1 mg/mL, opening the door to its use in agrifood formulations for reducing the use of chemical pesticides and preservatives.

Wildfires can have rapid and long-term effects on air quality, human health, climate change, and the environment. Smoke from large wildfires can travel long distances and have a harmful effect on human health, the environment, and climate in other areas. More recently, in 2018–2019 there have been many large fires. This study focused on the wildfires that occurred in the United States of America (USA), Brazil, and Australia using Cloud-Aerosol Lidar with Orthogonal Polarisation (CALIOP) and a TROPOspheric Monitoring Instrument (TROPOMI). Specifically, we analyzed the spatial-temporal distribution of black carbon (BC) and carbon monoxide (CO) and the vertical distribution of smoke. Based on the results, the highest detection of smoke (~14 km) was observed in Brazil; meanwhile, Australia showed the largest BC column burden of ~1.5 mg/m2. The meteorological conditions were similar for all sites during the fires. Moderate temperatures (between 32 and 42 °C) and relative humidity (30–50%) were observed, which resulted in drier conditions favorable for the burning of fires. However, the number of active fires was different for each site, with Brazil having 13 times more active fires than the USA and five times more than the number of active fires in Australia. However, the high number of active fires did not translate to higher atmospheric constituent emissions. Overall, this work provides a better understanding of wildfire behavior and the role of meteorological conditions in emissions at various sites.

The purpose of the work is to analyze the problems of using mining machines with diesel engines, the exhaust gases of which have a harmful effect on human health and the environment. Research methodology. The environmental problems arising from the use of mining machines, and environmental standards governing the use of diesel engines in different countries of the world are analyzed. Results. Environmental protection is one of the most important problems of humanity, since people’s lives, their health and well-being depend on its solution. The mining industry operates a huge amount of equipment with diesel engines: mining trucks, excavators, drilling rigs and other mining machines. Engine exhaust fumes contain toxic elements that have a significant impact on human health and the environment. The gas pollution of the working atmosphere entails the need to stop the quarry, and the deterioration of visibility on the highway also causes a partial or complete shutdown of the equipment until the content of harmful substances in the air drops to normal. Today, environmental requirements for a car engine are priority, so the global engine industry is aimed not only at increasing their performance, but also at significantly improving their environmental performance. The problem of air pollution by harmful substances contained in the exhaust of diesel engines is becoming global. To solve it requires the joint efforts of many countries. International conventions and the adoption of relevant standards serve as a tool for rapprochement in this area. Conclusions. Most countries in Europe, Asia and America are guided by similar standards for the content of harmful substances in exhaust gases. The EU in this regard is a kind of authority: it most often updates these indicators and implements strict legal regulation. Other countries are following this trend and are also updating emission standards.

Air pollution has become a serious public health problem globally. Recent studies support the harmful effect of air pollution on human health, in addition to scientific evidence that recognizes it as a human carcinogen. The buccal micronucleus cytome (BMC) assay is employed extensively to measure cytotoxic and genotoxic damage in a population exposed to environmental contamination. The objective of this study was to evaluate the cytotoxic and genotoxic effects in healthy young adults exposed to different levels of air pollution and to identify areas with air pollution rates above the regulatory limits. This study was performed through the BMC assay in oral mucosa samples from 80 healthy young adults from the Guadalajara metropolitan zone. Three highly contaminated areas were taken into account: Tlaquepaque, Miravalle, and Las Pintas. Las Aguilas, a less contaminated area, was used as a reference. The frequencies of nuclear abnormalities in the areas with the highest and lowest levels of air pollution were compared with the Mann–Whitney U test. In addition, an analysis of the concentration of environmental pollutants, particulate   matter ≤ 10   μ m (PM10), ozone (O3), nitrogen dioxide (NO2), sulfur dioxide (SO2), and carbon monoxide (CO), were carried out in the mentioned areas, in order to identify the events above the regulatory limits in a year period. The results showed that young adults exposed to a higher concentration of pollutants showed higher frequencies of nuclear abnormalities. The individuals from the areas of Tlaquepaque, Miravalle, and Las Pintas showed cytotoxic damage since statistically significant differences were found in the abnormalities of pyknotic nuclei (PNs), condensed chromatin (CC), karyorrhexis (KX), and karyolysis (KL). The individuals who showed the most cytotoxic damage were from the Las Pintas area with higher frequencies in nuclear abnormalities (PNs, CC, KX, and KL) ( p < 0.0001 ). Genotoxic damage was found in individuals from two zones, Miravalle and Las Pintas, with statistically significant differences in the abnormality of nuclear buds (NBUDs) ( p < 0.0001 ). Our results suggest that exposure to high levels of air pollution in healthy young adults has an effect on cellular and nuclear integrity and thus in human health, since areas with higher air pollution showed an increase in cytotoxicity, specifically in early and late markers of cell death (CC, KX, PN, and KL) and genotoxic damage (BUDs).

Water And Soil Pollution

Agricultural technology advancements are continuously taking place in India, as the progress of agricultural sector directly impacts a major proportion of population and its living condition. Farmers are interested to adopt new inventions and technologies in agriculture. Modern agricultural practices are significantly affecting human health and environment. The release of greenhouse gases such as carbon dioxide, methane and nitrous oxide are adversely affecting biodiversity and increasing air, water and soil pollution. Agricultural residue management, use of pesticides and insecticides, inorganic manure, chemical fertilizers leads to harmful effect on human health and increasing environmental pollution. Recent agriculture trends emphasizes on enhancing agricultural production in terms of quantity in less time, overlooking its adverse affects. In this paper we have analyzed the negative effects of modern agricultural practices on human health and environment. It leads to decline in soil fertility, loss of biodiversity, climate change, air, water and soil pollution, environmental degradation etc. Our farmers are now adopting modern agricultural techniques, using chemical fertilizers, pesticides, insecticides, expanding irrigation facilities, using high yielding varieties of seeds, modern machines, varying crop sequences etc. But these efforts of expanding food supply in less time is taking place at the cost of human health and environment degradation. Spray of harmful chemicals on crops not only pollutes underground water and air but also bad for human and animal health. Non harmonious, unwise and unsustainable agricultural practices have a considerable impact on environment and also harmful for living beings.
