Environmental Fate of Maneb

نویسنده

  • Elizabeth Downing
چکیده

The fungicide maneb is moderately soluble in water and undergoes hydrolysis. Its main products for hydrolysis and photolysis are EU, ETU, EBIS, and glycine. Microbial degradation of maneb represents a minor breakdown route. Aquatic metabolism yields the main products EBIS, ETU, and EU. A field dissipation study showed that maneb persisted in soil for one week when applied at 100 ppm. Maneb is adsorbed strongly to most soils and is only slightly mobile. There is negligible mobility of maneb in the air since its vapor pressure is very low. Maneb is translocated primarily in the xylem of plants yielding the major metabolite ETU. There has been no evidence of maneb entering groundwater. Maneb is not seen as a likely contaminant of surface water and has not been monitored.

Sorption behaviour of maneb in the agriculture soils and its correlation with soil properties

Maneb is a broad spectrum fungicide, often reported as a carcinogenic, teratogenic and neurodegenerative agent. Thus, the occurrence of maneb at non-targeted sites is a cause of concern. The present study investigates adsorption– desorption behaviour of maneb in the agricultural soils to know its fate, mobility and availability in the soil. The sorption study was carried out by batch equilibrat...

Potentiated and preferential effects of combined paraquat and maneb on nigrostriatal dopamine systems: environmental risk factors for Parkinson's disease?

The absence of any compelling basis for a heritable basis of idiopathic Parkinson's disease (PD) has focused attention on environmental exposures as causative agents. While the herbicide paraquat has repeatedly been implicated, its impact on dopamine systems following systemic exposures is equivocal. The restricted focus on paraquat also ignores the extensive geographical overlap of its use wit...

The gestational environment and Parkinson's disease: evidence for neurodevelopmental origins of a neurodegenerative disorder.

Parkinson's Disease (PD) is a degenerative neurological disorder that typically manifests symptoms in late adulthood, after loss of dopaminergic neurons in the nigrostriatal system. A lack of heritability for idiopathic PD has implicated adulthood environmental factors in the etiology of the disease. However, compelling evidence from animal models published within the past few years has shown t...

Paraquat, but Not Maneb, Induces Synucleinopathy and Tauopathy in Striata of Mice through Inhibition of Proteasomal and Autophagic Pathways

SNCA and MAPT genes and environmental factors are important risk factors of Parkinson's disease [PD], the second-most common neurodegenerative disease. The agrichemicals maneb and paraquat selectively target dopaminergic neurons, leading to parkinsonism, through ill-defined mechanisms. In the current studies we have analyzed the ability of maneb and paraquat, separately and together, to induce ...

Early Environmental Origins of Neurodegenerative Disease in Later Life

Parkinson disease (PD) and Alzheimer disease (AD), the two most common neurodegenerative disorders in American adults, are of purely genetic origin in a minority of cases and appear in most instances to arise through interactions among genetic and environmental factors. In this article we hypothesize that environmental exposures in early life may be of particular etiologic importance and review...
