Analysis of non-metallic contaminants from amphibian environment in Sindh, Pakistan

Abstract

Water pollution is a major threat that causes amphibians to decline rapidly. Therefore present study was carried out in three Talukas of District Jamshoro to investigate pollution rate in amphibian ambient through analysis of nonmetallic contaminants i.e. Sulphate (SO4), Phosphate (PO4), Nitrite (NO2) and Nitrate (NO3) from 16 inhabitations during 2011. The ultraviolet-visible spectroscopy revealed whole study area containing high level of SO4 (432.5±149.4), PO4 (400.5±136.7), NO2 (3.0±2.7) and NO3 (6.0±3.5) making environment chemically contaminated that may lead amphibians to mortality. Seasonal fluctuations exhibited extreme concentration of all the studied parameters from May to August which may create environment more difficult for the normal development of eggs and larvae as breeding and hatching takes place during this time. This destructed environment requires urgent management for the conservation of amphibian fauna in District Jamshoro.
