The water and sediment samples from the Sulejow Reservoir and Pilica River (Central Poland) were analysed for nutrients: total phosphorus (TP), total nitrogen (TN) and the suspended particulate matter (SPM) and dioxin-like PCBs (dl-PCBs) concentration. Dl-PCBs were detected in sediments from all seven sampling locations with mean concentrations of 14.29 ng kg−1 dry weight (d.w.). The lowest concentration was recorded in the sediment collected below the Sulejow Reservoir (PR5; 2.92 ng kg−1 d.w.) and the highest in the sample collected from the mouth section of the Pilica River (PR7; 26.30 ng kg−1 d.w.). The 29% reduction of the total dl-PCBs concentration – from 9.21 ng kg−1 d.w. in the middle section to 6.54 ng kg−1 d.w. in the dam section of the Sulejow Reservoir – demonstrated the hydraulic transport and deposition of measured pollutants in the reservoir's sediments. The results obtained also revealed the reduction of nutrients and the SPM concentrations. A 45% reduction of SPM, 28% reduction of TP and 34% of TN was observed between the water inflow and outflow from the Sulejow Reservoir.

Abstract. We present the first measurement of nitrogen isotopic composition (δ15N) in suspended particulate matter (SPM) of the surface Bay of Bengal (BOB) at 24 different locations during pre- (April–May 2003) and post- (September–October 2002) monsoon seasons. The δ15N of particulate organic nitrogen (PON) in surface suspended matter of coastal as well as northern open BOB shows signatures of a two end-member mixing between continental inputs and marine sources. Dilution by the organic and detrital continental material brought in by rivers leads to consistently lower δ15N, evident from the relationship between surface salinity and δ15N. δ15N of surface PON of open ocean locations during both seasons, and also at coastal locations during pre-monsoon suggest the nitrate from deeper waters as a predominant source of nutrient for planktons. The depth profiles of δ15N of SPM during pre-monsoon season at nine different locations are also presented. These indicate an increase in δ15N by a maximum of 2.8‰ between euphotic depth and 300 m, which is lower than that observed in the eastern Indian Ocean, indicating the role of higher sinking rates of particles ballasted by aggregates of organic and mineral matter in BOB.

<p><strong>Objective: </strong>Aim of the study was to screen the suspended particulate matter for their role in enhancing angiogenesis employing crown gall tumor assay.</p><p><strong>Methods: </strong>Particulate matter (PM<sub>10</sub>) samples were collected, on glass fiber filter paper at the rate of 1.12–1.14 m<sup>3/</sup>min for 8 hr using high volume sampler, from six different sites of Amritsar city. Aqueous extracts of suspended particulate matter were prepared using a mechanical shaker for 24 hour and the filtrate was centrifuged and lyophilized.</p><p><strong>Results: </strong>Maximum (34.67±1.764) tumors were induced by samples collected from Crystal chowk whereas tumor inducing ratio (TIR) was found to be comparably high for two sites <em>viz.,</em> Crystal chowk and Bhandari bridge.</p><p><strong>Conclusion: </strong>High tumor inducing ratio at the above-mentioned sites was correlated to high traffic emission from automobile exhaust. Crown gall tumor assay has been proved to be rapid, economical and reliable screening assay for angiogenesis agent.</p>
