Karnataka coast is subjected to several factors of pollution due to several anthropogenic activities. Such activities vary between other development aspects and fishing harbour. Studies on water quality parameters in seawater and heavy metals in wedge clam, Donax scortum (Family: Donacidae) were carried out from Padukere beach. Significant variability in the water quality parameters and heavy metals was observed in Padukere. The concentration of Mn was lower during pre-monsoon followed by post monsoon and monsoon, whereas the concentration of Zn was found to be high during post monsoon season followed by monsoon and pre-monsoon. Zn concentration was the highest in D. scortum compared to earlier studies from other geographical regions. The dendrogram indicated that the pattern clustering showed that seasonal variations in environmental variables and metals were determined by seasonal effects, and the influx and nature of water from Udayawara river. The dendrogram of temporal clustering of monitoring periods at Padukere showed that variation in the environmental parameters and metals in D. scortum were only determined by seasonal effects with transition months. PCA was used to interpret relationships between variables. Perhaps the distribution of metal concentrations is by the nature and frequency of discharge.

重金属的季节性浓度和环境参数，以印度最大的楔形蛤Don（Donax scortum）为参考（Linnaeus，1758年）

卡纳塔克邦海岸由于几次人为活动而受到多种污染因素的影响。这些活动在其他发展方面和渔港之间有所不同。在帕多克尔海滩上研究了楔形蛤Don（Donax scortum，家庭：Donacidae）的海水和重金属中的水质参数。在帕德克雷，观察到水质参数和重金属的显着变化。季风前，季风后和季风中的锰含量较低，而季风后季风，季风和季风前的锰含量较高。锌浓度在角皮果蝇中最高与其他地理区域的早期研究相比。树状图表明，模式聚类表明环境变量和金属的季节性变化是由季节影响以及来自Udayawara河的水的流入和性质决定的。在Padukere监测周期的时间群集的树状图显示，在环境参数和金属中的变异D. scortum只通过与过渡个月季节影响来确定。PCA用于解释变量之间的关系。金属浓度的分布可能取决于放电的性质和频率。
