Organochlorine pesticides, such as HCH (Hexachlorocyclohexane) and DDT (dichloro diphenyl trichloro ethane) and its metabolites were analysed in commercially important fishes, collected from the Dadar fish market (Mumbai) in July 2011. Total DDT concentration varied between 14.88 and 58.30 ng.g-1 in the Lisa parsia and Chirocentrus dorab respectively. The minimum and maximum concentrations of t...

The effects of insecticides (endosulfan, HCH) and heavy metals (copper and zinc) were studied on survival and duration of the moult cycle of larvae and megalopa of a common mangrove crab, Macrophthalmus erato, that inhabits Pitchavaram mangroves, southeast coast of India. In chronic toxicity test, percentage of survival from hatchling to megalopa stage at different concentrations of endosulfan ...

Five sample of each vegetable in each location per month was collected from three markets of Jorhat districts for three months. Three markets are Jorhat vegetable market, Lichubari vegetable market and Teok vegetable market of Jorhat district. The vegetable species are Tomato, Cabbage, Cauliflower, Brinjal, French bean, Cow pea and Okra. Individual species of samples were mixed and analyzed in ...

Soils are the major terrestrial reservoir of persistent organic pollutants, and thus net volatilization from soil, when it happens, may exert a control on the atmospheric occurrence and variability of organic pollutants. Here, we report and discuss the concentrations of legacy organochlorine pesticides (OCPs) such as hexachlorobenzene (HCB), hexaclorocyclohexanes (HCH) and dichlorodiphenyltrich...

The cause of Parkinson's disease (PD) remains elusive, but environmental chemical exposures have been postulated to be involved in the etiology of PD. We examined the association between the persistent organochlorine pesticides (OCPs) and PD in the North Indian population. This case control study included 70 PD and 75 control subjects in the age group of 50 to 85 years. Blood samples were colle...

The organochlorine pesticides (OP) are very stable molecules, due to this stability; they are very resistant in the environment and highly related to fat tissues with a wide diffusion property and an average time life higher then 10 years. We studied sediments (November 2001, April and June 2002) and organisms collected in April and July (2002) from the lacustric zone of Metzitlán, Hidalgo, Mex...

OBJECTIVE To estimate the degree of internal exposure to organochlorine pesticides (persistent organic pollutants, POP) among inhabitants of an open-air dump. METHODS This was an observational study with simultaneous measurement and control, in which the criterion for subjects was that they dwelled in an area contaminated by POP and the effect of such contamination was the concentration of su...

The aim of the study was to assess effects therapeutic ultrasound (US) on oxidative stress (OS)-induced changes in cultured human chondrocytes (HCH). For this, monolayer HCH were randomized three groups: a control group (CG), exposed OS (OS group), and US (US-OS group). exposure performed prior induction by hydrogen peroxide. Transmission electron microscopy (TEM) used ultrastructure. inflammat...

Persistent organic pollutants (POPs) present in the living environment are thought to have detrimental health effects on the population, with pregnant women and the developing foetus being at highest risk. We report on the levels of selected POPs in maternal blood of 155 delivering women residing in seven regions within the São Paulo State, Brazil. The following selected POPs were measured in t...

Organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs) were studied to determine occurrence, levels and spatial distribution in the marine atmosphere and surface seawater during cruises in the German Bight and the wider North Sea in spring and summer 2009-2010. In general, the concentrations found in air are similar to, or below, the levels at coastal or near-coastal sites in Eur...
