    Endosulfan is highly bioaccumulative and is expected to biomagnify. At constant exposure it is very toxic to all organisms. Concentrations of 1 mg/l are toxic to all marine organisms, while concentrations of only 0,04 µg/l are already toxic for crustaceans. In rats doses above 18 mg per kg body weight can prove lethal. A review by Francisco Sánchez-Bayo and Kris A. G. Wyckhuys in the journal Biological Conservation analysed 73 long-term insect surveys that had shown decline, most of them in the United States and Western Europe. While noting population increases for certain species of insects in particular areas, the authors reported an annual % loss of biomass. Toxicity of endosulfan in fish EFSA Journal ;9(4) 6 EVALUATION 1. Introduction Endosulfan is an organochlorine pesticide patented in the mid s. Technical grade endosulfan is mainly composed of a mixture of two biologically active stereoisomers named α-endosulfan and β-endosulfan in a ratio of 70 % to 30 % respectively. Endosulfan has an acute LD 50 to the rat of 30 mg/kg in alcohol suspension, 70 mg/kg in aqueous suspension, and mg/kg in oil Ref. For fish the LC 50 value is ppm (Ref. There are reports of workers becoming ill from inhalation of dust from endosulfan.

Saradha. Biological And Effects Of Endosulfan & Dimethoate On Marine Molluscs a About the Book: Biological And Effects of Endosulfan & dimethoate on marine mollusks The work is mainly devoted to the study of ecology, breeding biology andbiochemical composition of the Tellinids (Marine bivalves) Endosulfan is a ubiquitous environmental contaminant.

The chemical is semivolatile and persistent to degradation processes in the environment. Endosulfan is subject to long-range atmospheric transport, i.e. it can travel long distances from where it is used.

Thus, it occurs in many environmental al formula: C₉H₆Cl₆O₃S. There is experimental evidence of adverse effects of endosulfan on the male reproductive system, but there are no human data. Therefore, we undertook a study to examine the relationship between environmental endosulfan exposure and reproductive development in Cited by: Case study – Effects of aerial spraying of endosulfan on the residents of Muliyar Panchayath.

Endosulfan is an insecticide that is applied extensively to coffee, tea, and cotton crops, among others. In its commercial form, endosulfan is composed of two stereoisomers, α and β endosulfan, in a ratio.

The study of Endosulfan effects showed larger abnormality such as mental retardation, cancer and infertility Biology and effects of endosulfan and dimethoate on marine molluscs book the victims. But the pesticide and fertilizer industries were very fast to refuse the studies.

Endosulfan is manufactured and distributed in India by Hindustan Fertilizers limited. Endosulfan has been banned in Kerala. Endosulfan is a chlorinated hydrocarbon insecticide of the cyclodiene subgroup which acts as a contact poison in a wide variety of insects and mites.

It can also be used as a wood preservative. It is used primarily on food crops like tea, fruits, vegetables and on grains.

The mantle of snails exposed to and mg/l concentrations of endosulfan for 10 days showed that the numbers of mucocytes and protein cells were increased, and epithelium cells were desquamated by:   The health effects of endosulfan depend on how much endosulfan you are exposed to and the length of that exposure.

Environmental monitoring data suggest that any endosulfan levels the public might encounter through direct contact or through water, soil, or food are generally low, much lower than animal study levels.

In this study, we examined the effects of 37‐d exposure to the agrichemicals atrazine (4, 40, and μg/L), carbaryl (, 5, and 50 μg/L), endosulfan (, 1, and 10 μg/L for 31 d and10, and μg/L for the last 6 d), and octylphenol (5, 50, and μg/L) and to a solvent control on streamside salamanders (Ambystoma barbouri) in Cited by: Inthe APVMA released the Endosulfan interim report, which recommended a number of changes to the use of endosulfan to reduce risks to the environment and worker safety and to reduce residues in changes included: declaring endosulfan products to be restricted chemical products; requiring users of endosulfan to undertake specified training.

But with endosulfan having one of the highest hazard ratings among pesticides, ill effects on the living organisms in affected areas can be significant.

Evaluation and interpretation of environmental data on endosulfan in Arctic regions • Human dietary risk was concluded to be generally negligible except with unrealistic, extreme worst-case assumptions (coincidence of very heavy reliance upon marine mammals and fish characterised by 99th centile endosulfan residue profiles).

Health effects reported from exposure to endosulfan in occupational settings include systemic toxicity, eye and skin irritation, respiratory effects and headaches (NRA, ). No information was available on the levels of exposure required to produce these Size: KB.

Studies of the effects of Endosulfan on animals suggest that long-term exposure to Endosulfan can also damage the kidneys, testes, and liver and may possibly affect the body's ability to fight infection. However, it is not known if these effects also occur in humans.

It is unknown whether Endosulfan can cause cancer in humans.the establishment and implementation of programmes at all levels of education on the importance of the marine environment and the impact of pollution from agricultural activities.
