Assessment of concentration and distribution of total mercury and polychlorinated biphenyls in Green Bay, Wisconsin, USA

Under the 1987 Great Lakes Water Quality Agreement, the lower Green Bay and Fox River estuary have been labeled as areas of concern due to the contamination of mercury and polychlorinated biphenyls (PCBs) from industrialization. These pollutants pose substantial health and environmental hazards for the Green Bay region. The PCBs reported in this region, including Aroclor 1242, are known to trigger carcinogenic responses in animals and mercury targets the central nervous system and vital organs. Furthermore, these compounds are extremely difficult to remove from the environment once introduced. Extensive remedial actions have been implemented including dredging sediments in the Lower Fox River from DePere to Green Bay. The purpose of this study is to assess the concentration and distribution of Aroclor 1242 and total mercury in the Green Bay region sediments and pore waters and to assess the impact of interventions and the natural rates of change previously found.

Evaluation of Different Gladiolus (Gladiolus grandiflorus) Cultivars in Terms of Spike Quality under Allahabad Agro Climatic Condition

The present experiment was conducted during October 2011 – April 2012 in the Department of Horticulture, Sam Higginbottom Institute of Agriculture Technology and Science, Allahabad, (U.P.). The experiment of design was randomized block design consisting 11 treatment with 3 replication, with a view to find out the overall performance of different cultivars of Glodiolus viz. Panjab Morning (T1), Green Bay (T2), Noualux blue (T3), American Beauty (T4), Priscilla (T5),White Prosperity (T6) Red Majesty (T7), Summer Shunshine (T8) Delhi local (T9), Noualux (T10), Candyman (T11),. On the basis of different growth and yield parameters the maximum days for first floret durability (6.16). were recorded by White Prosperity (T6) followed by American Beauty (T4) (5.76). The maximum number of spike length (95.13cm) was obtained in White Prosperity (T6) followed by Red Majesty (T7) (94.16). The maximum weight of spike (64.40 g) was observed in White Prosperity (T6) followed by American Beauty (T4) (64.33g). The maximum floret diameter (12.63cm) was found in Summer Pearl (T8) followed by White Prosperity (T6) (12.53cm). The maximum number of floret per spike (18.00) was found in White Prosperity (T6) followed by American Beauty (T4) (17.73). The maximum number of spikes per plant (5.33) was observed in Delhi Local (T9) followed by White Prosperity (T6) (1.3). Which can be recommended for cultivation in Allahabad agro-climatic condition.
