Abstract

The leaves of two plant species, namely Saraca indica and Lantana camara are examined to determine the composition and levels of trace elements in particulate matter having size less than 10 [mu]m ([PM.sub.0]) of the atmospheric particles that are released from the vehicles.

Abstract

The work presented here analyzed water samples from three sewage treatment plants which regularly discharge into the River Ganga. Biological oxygen demand and dissolved oxygen values were well above the permissible limit at all sites, and were recorded as being at maximum at Dinapur sewage treatment plant. Heavy metals (Zn, Cu, Cd, Pb, Cr) in disposed effluents were above permissible limits at all three sites. Likewise, the most probable number index of E. coli in water samples and coliform counts were recorded as being higher in irrigated water samples and vegetables, indicating a serious health hazard posed by intense microbial and faecal pollution. It was recommended that an integrated approach of phytoremediation with aquatic macrophytes and ozonization of wastewater be adopted to curb the heavy metals and microbial pollution based on these recent research investigations.

Abstract

A total of 144 samples of water used for irrigation were collected from Dinapur, DLW sewage treatment plant and river water of Ganga at Rajghat and 258 irrigated vegetable samples were collected from nearby agricultural fields in the close vicinity of three treatment plants and examined using standard procedures for coliform and viable counts and the presence of Escherichia coli, Salmonella, Clostridium and Vibrio during the winter and rainy seasons. Irrigation water from Rajghat drain had significantly higher coliform counts by location and season than the water from the Dinapur and DLW. Although all the vegetables had coliform counts higher than the recommended standard (range 3.40 - 6.38 log10 cfuml-1), spinach and cabbage had significantly higher (p < 0.05) counts compared to other vegetables during the dry season. Salmonella was significantly more likely to be detected during the rainy season than during the dry season. Contaminated vegetable intake may pose a serious threat to human health.
