Among the possible sources of environmental contamination by plant protection products, the use of air blast sprayers in orchards and vineyards can be very critical. The evaluation of the vertical distribution pattern is a crucial test to achieve a good quality of spray application. The aim of the paper was to compare the performance of a vertical lamellate patternator versus a horizontal lamel...

 Background: Plastic and polymeric materials remain in the soil given the fact that they are derived from petroleum resources. However, such pollution has created a special challenge for human societies. The use of biodegradable packaging has received more attention. The general purpose of this study was to investigate the use of a mixture film of whey protein concentrate and reinforced hydroxy...

in this research a pot experiment was carried out to investigate the remediation ability of e. camaldulensis dehnh inlead-zinc (pb-zn) contaminated soil. the study also investigated the effects of ethylenediaminetetraacetic acid(edta) and diethylenetrinitrilopentaacetic acid (dtpa) on the phytoremediation efficiency of the plant species, andharvest time as a suitable dose of chelating agents wa...

thechah nimeh reservoirs of sistan is as one of the main water sources of zabol city used for drinking, agriculture, industry and livestock purposes. this study aimed to determine the contribution of the natural and concentration factors of heavy metals such as cd, pb and cu in sediment of chah nimeh of sistan. the concentrations of heavy metals in surface sediments were studied in six stations...

the continuous addition of industrial, municipal, and agricultural effluents to the environment has led to a great increase of toxic pollutants. it is well known that these pollutants are hazardous to animals, plants, microorganisms, and other living organisms including humans. as a result, effective technologies should be developed to remove these contaminants. biological remediation, as an ec...

In 2008, the statute authorizing the Minnesota Pollution Control Agency (MPCA) to issue air permits was amended to include a unique requirement to analyze and consider "cumulative levels and effects of past and current environmental pollution from all sources on the environment and residents of the geographic area within which the facility's emissions are likely to be deposited." Data describin...

BACKGROUND Environmental health research employs a variety of metrics to measure heat exposure, both to directly study the health effects of outdoor temperature and to control for temperature in studies of other environmental exposures, including air pollution. To measure heat exposure, environmental health studies often use heat index, which incorporates both air temperature and moisture. Howe...

BACKGROUND Indigenous American communities face disproportionate health burdens and environmental health risks compared with the average North American population. These health impacts are issues of both environmental and reproductive justice. OBJECTIVES In this commentary, we review five indigenous communities in various stages of environmental health research and discuss the intersection of...

In the manufacture and use of the several thousand chemicals employed by technological societies, portions of these chemicals escape or are intentionally introduced into the environment. The behavior, fate, and to some extent the effects produced by these chemicals are a result of a complex interaction of the properties of the chemical with the various processes governing transport, degradation...

In policymaking on environmental health, it is often assumed that the entire population is exposed to and reacts to environmental contaminants in a similar manner. However, this assumption is misguided, especially where children are concerned. This article presents the scientific basis for the impacts of the environment on children, showing how children are different from adults in the ways in ...
