Plants need certain conditions that represent their living environment. When the living environment provides the conditions required by the plant, it will grow and develop properly. The growth and development of plants involve environmental factors, which represent those constituent elements of the natural environment, which actively intervene in plants’ life. The present work shows the characteristics of an agricultural soil, contaminated with heavy metals (Cu, Pb and Zn) in different concentrations, which has been divided into pots, in which were thereafter planted vegetable seedlings (tomatoes, cucumbers, parsley, spinach, carrots, radishes). During the plants’ growing time, the temperature and humidity of the air inside the greenhouse, as well as the humidity and pH of the soil, were monitored. The growth and the development of the plants under certain conditions were also tracked, until the end of the growing period. The results of monitoring the plants’ growth and development are important in assessing the impact of the contamination over the soil and the plants.

Water Plant

Many plants are capable of accumulating heavy metals (called hyperacumulators), one of which is the water hyacinth Eichhornia crassipes Mart. The roots of this water plant naturally absorb pollutants, including heavy metals such as Pb, Hg, Zn, Co, Cd, and Cu and can be used for wastewater treatment. The aim of this study was to assess the influence of heavy metals on growth and development of water hyacinth and to determinate the uptake capacity of heavy metals of this species. It was evaluated for its effectiveness in reducing pollution potential in wastewater. From the combination of experimental factors 11 variants resulted. The results showed that Eichhornia absorbed a high quantity of Pb (504 mg/kg dry matter) and Cu (561 mg/kg dry matter) in their roots. More Cu accumulated in the root compared to Pb. The level of Zn absorption was lower in roots (84 mg/kg dry matter) and also in stem plus leaves (51 mg/kg dry matter). A high quantity of Cd (281 mg/kg dry matter) was removed from stem plus leaves of Eichhornia while the level of Co was very low (45 mg/kg dry matter). Regarding the growth and development of this plant it was found that in tanks with Pb plants had a better development and had flowers also, and in the case of Cd, Co, Cu at a double dose of maximum admissible limits, the plants died and the growing period was shorter.

The Impact

Counties have expanded the scope of their activities in the economic development process. However, limited research exists of the factors that influence economic growth and development trends of these unique communities. The primary focus of this case study analysis is to determine whether form of government has an impact on county economic growth and development trends while controlling for environmental context and demographic characteristics in Alabama, Pennsylvania, Illinois, and Washington. To empirically test the impact that county form of government and environmental factors have on local economic growth and development trends, ordinary least squares regression is used. The results of this study show that form of government has only a marginal impact on county economic growth and development trends. County environmental factors are found to have a more substantive impact on the economic growth and development trends of counties across these four states.

The Impact

The modern concept of gardening involves the use of large amounts of inert materials, different designs, and modern forms. Widespread urbanization of territories entails almost complete exclusion of green spaces, landscapes mediocrity and aggressive environments. All this has a negative effect not only on the environment but also has a negative impact on human. Reduced Stress resistance reduces and the working population decreases, the percentage of various diseases increases. In this paper we consider the question of proposing how to tie urbanized area with the surrounding environment. Along with urbanized areas a suburban town, so-called "second home" play a major role in people´s lives. Accomplishment of such areas should include elements that allow a person to relax as much as possible by working days. Since the cottage villages are composed of model homes, it suggests the monotony plan of surrounding territory. The best decoration of such areas is the use of tree and shrub vegetation, as well as decorative flower crops. Flower decoration of adjoining areas refreshes dull monotony of typical households. Given the impact of current trends in landscape design, we note the following aspects of the areas design. Rectilinear forms of trees and bushes are disappearing as the most fashionable style decision is a landscape of the site. Manor house in the Russian style looks particularly attractive, as historically Russian style was associated with the natural environment. Cottage village is ideally located surrounded by forest on the banks of a natural lake. The objective of our work was to unify the territory of cottage settlement with the surrounding ecosystem. For small areas "small" gardens are ideal decision. We also offer to create more comfortable living environment to emphasize the conditional zoning with green hedges. The paper presents a range of plants that will accentuate central Russian landscape and create coherent whole perception of the village and the environment.

<p><em>The impact of the environment on the American Revolution in New Jersey cannot be understated as environmental factors ranging from climate to crop yields to geography all intensely impacted the course of the Revolution. This talk, delivered on November 18<sup>th</sup> at the opening reception of the NJ Historical Commission’s 2016 NJ Forum, explores the relationship between the natural environment and military and political policies through the eyes of William Livingston, New Jersey’s first governor. Throughout the conflict, the environment became a constant actor and foil to Livingston, forcing him to make political decisions in tandem with not only British movements but more frequently, owing to climatic, geographic, or agricultural factors. In addition to looking at Livingston, the article examines the interplay between Livingston and his own conceptions on the environment from his pre-revolutionary past. Finally, the article discusses how average New Jerseyans understood the role of his revolutionary government in the context of various environmental factors. Most Jersey farmers and landless laborers based their support for the revolutionary movement not on ideology but on environmental factors that constantly challenged their loyalty to both sides.</em></p>

The Impact

Background and Aim: Many environmental factors exist that influence embryonic development which is missing in the poultry industry, such as light in incubation facilities or hatcheries. Light plays an important role in the growth and development of chick embryos, whereas dark environments can lead to hatching failure or embryo distortion. Therefore, this study aimed to demonstrate the importance of light and its various colors on the growth and development of broiler chick embryos. Materials and Methods: Four treatments were used to study the impact of various light colors on the growth of embryos and their neurophysiological traits: Dark without light (D), red light (RL), blue light (BL), and green light (GL), with three replicates per treatment (25 eggs/replicate) for a total of 300 fertile Ross 308 eggs. Each treatment was assigned to one incubator (75 eggs/incubator), whereas all other conditions were kept the same. Results: The results showed a significant increase (p<0.01) in embryonic development for embryo weight, chick body weight, hatchability, and embryo index for RL, BL, and especially GL. RL, BL, and especially GL significantly increased (p<0.01) neurophysiological traits of the neurons, brain weight, and brain index. Conclusion: The use of light during the embryonic period affects the development of the embryo and its neurophysiological traits.

The effort to maintain the balance of the natural environment is the responsibility of all humans on earth. The Waso Community (Anak Waso Community, AWAS.com) and the Waso indigenous community have been trying to carry out their responsibilities by carrying out reforestation activities for three years. To see the extent of these efforts carried out and get its impact, it is necessary to do social research. The main objective of this social research is to observe and evaluate comprehensively the steps of the Waso children's community in carrying out reforestation activities for three years in the Bangka Poa region, as well as the impact of the activities carried out. To describe the efforts of the Awas.Com community in protecting the environment, researchers conducted social research carried out using the Planning, Organizing, Acting, Impact (POAI) method. The research results illustrate that this reforestation activity has shown a positive impact in the form of the recovery of the natural conditions of the Bangka Poa region and the stable water debit in several springs. The research study also looks at and evaluates that reforestation activities for three years in a row have had a direct or indirect impact on the growth and development of ecological, sociological, economic and religious awareness and responsibilities in the community and Waso young generation.

The Impact

Gene expression is a complex and quantitative trait that is influenced by both genetic and non-genetic regulators including environmental factors. Evaluating the contribution of environment to gene expression regulation and identifying which genes are more likely to be influenced by environmental factors are important for understanding human complex traits. We hypothesize that by living together as couples, there can be commonly co-regulated genes that may reflect the shared living environment (e.g., diet, indoor air pollutants, behavioral lifestyle). The lymphoblastoid cell lines (LCLs) derived from unrelated couples of African ancestry (YRI, Yoruba people from Ibadan, Nigeria) from the International HapMap Project provided a unique model for us to characterize gene expression pattern in couples by comparing gene expression levels between husbands and wives. Strikingly, 778 genes were found to show much smaller variances in couples than random pairs of individuals at a false discovery rate (FDR) of 5%. Since genetic variation between unrelated family members in a general population is expected to be the same assuming a random-mating society, non-genetic factors (e.g., epigenetic systems) are more likely to be the mediators for the observed transcriptional similarity in couples. We thus evaluated the contribution of modified cytosines to those genes showing transcriptional similarity in couples as well as the relationships these CpG sites with other gene regulatory elements, such as transcription factor binding sites (TFBS). Our findings suggested that transcriptional similarity in couples likely reflected shared common environment partially mediated through cytosine modifications.

Abstract Soil can be contaminated by the accumulation of heavy metals and metalloids through emissions from rapidly developing industrial areas. Due to the possibility of chemical change (speciation) and their bioavailability, the presence of toxic metals in the soil can greatly inhibit the biodegradation of organic contaminants. The researchers aimed to analyse the effect of heavy metal levels in agricultural soil on chlorophyll levels in agricultural crops through a meta-analysis method which is expected to provide results in the form of a summary of data that already exists in journals that have been published so far. Here we present a meta-analysis of 6 studies (56 data collected) published between 1997 and 2020 that reported the effects of heavy metal content on plant chlorophyll content. Based on the meta-analysis of the effect of heavy metal exposure in agricultural soil on the chlorophyll content of agricultural crops, the value “effect size overall” was -0.285 in the range of -0.380 to -0.190, where most of the values “effect size” were on the left. Plants growing on soil contaminated with heavy metals result in decreased growth due to changes in physiological and biochemical activities, especially when heavy metals inhibit plant growth and development. Furthermore, environmental risk assessment due to mercury exposure is very important to control the transport and accumulation of mercury in the biosphere to reduce the impact of mercury on the environment.
