Micropollutants and emerging substances pose a serious problem to environmental sustainability remediation, due their widespread use applications in everyday life. This group of chemicals is diverse but with common toxic harmful properties. Their concentration the environment often very low; however, recalcitrant nature, they are persistent air, water, soil. From an engineering point view, chal...

The levels and distribution patterns of the selected organochlorine pesticides (OCPs=p,p'-DDT, o,p'-DDT, p,p'-DDE, p,p'-DDD, alpha-, beta-, gamma- and delta-HCH) in surficial sediments from the Haihe River and Dagu Drainage River of Tianjin were investigated by means of gas chromatography coupled with micro-electronic capture detector (GC-microECD). Concentrations of OCPs in the sediments from ...

Pesticides are a group of chemicals made for the purpose of killing or otherwise deterring “pest” species. The word pesticide may refer to insecticides, herbicides, fungicides, or other pest control formulations. Pesticides are inherently toxic and often associated with adverse health effects in non-target organisms.1 Organochlorine pesticides are a large class of multipurpose chlorinated hydro...

due to the uncensored use of pesticides in the agricultural regions of lebanon, the contaminationrisks of drinking water by organic residues increase periodically in planting seasons. no previous work havebeen considered in north lebanon plain concerning pesticide pollution though it is the second agriculturalzone in lebanon with an excessive activity. in this context, the aim of this study was...

For Canadian Arctic indigenous populations, marine mammal (MM) traditional foods (TFs) represent sources of both important nutrients and hazardous environmental contaminants. Food preparation is known to impact the nutrient and environmental contaminant content of processed items, yet the impacts of preparation on indigenous Arctic MM TFs remain poorly characterized. In order to determine how t...

Chemical analyses were performed on one hundred and twenty of the most popular varieties of fish products (smoked fish, salted fish, and marinated fish) of the fish market in Poland. The contents of the nutritive substances of fish products (protein, micro- and macronutrients, vitamins A(1), D(3), E, and fatty acids) and the chosen contaminant (toxic metals--mercury, cadmium, lead, arsenic; dio...

Abstract Background: poisoning is one of the most common medical emergencies. Every year many people refer to emergency wards due to poisoning and some of them are treated and some die because of severe complications. Most patients who refer to emergency wards are those who commit intentionally to suicide. This study is conducted to determine the prevalence of poisoning with pesticide (organop...

Organic pollutants have grown to be a serious global problem because of their massive creation, widespread application, and eventual discharge. Due biomagnification, accumulation, harmful acute chronic impacts on all living things, these substances significantly increased the load ecosystem its potential threats. Reducing risk factors associated with organic contaminantsthrough rhizospheric mic...

Organochlorine pesticides have been used in Mexico in malaria control programs and against ectoparasites. The objective of this study was to compare the levels of organochlorine pesticides: HCB, α-β-γ-HCH, pp'-DDE, op'-DDT and pp'-DDT in adipose tissue of female inhabitants from three Mexican states: Veracruz, Puebla and Tabasco. Data analyses indicated higher β-HCH levels in Puebla inhabitants...
