Abstract:
Unmanaged plastic debris from both terrestrial and aquatic sources is causing havoc on Indian coastlines. Tajpur Beach and Haliday Island were selected as two distinct coastal ecosystems in West Bengal for inventorying sighted macro-plastics, aiming to assess their distribution and compare pollution levels. This study employs a comprehensive methodological approach, integrating field-based observations along with lab-based measurements, and information derived from geospatial analysis. Total 34 random points across two study sites were considered for the physical, chemical, and biological characterization of macro-plastics to assess their relative abundance. Areas with higher human footfalls exhibited greater accumulation of plastic debris, with polypropylene, either alone or in combination with polyurethane and polystyrene, identified as highly toxic. Fragmented plastic debris was prevalent at both test sites, yet undisturbed Haliday Island exhibited an abundance of less fragmented materials. Emphasis was also given on implementing appropriate management regimes to achieve plastic-free diverse coastal landscapes.
摘要:
来自陆地和水生来源的未经管理的塑料碎片正在印度海岸线上造成严重破坏。Tajpur海滩和Haliday岛被选为西孟加拉邦的两个不同的沿海生态系统,用于清点有远见的宏观塑料,旨在评估它们的分布并比较污染水平。这项研究采用了全面的方法论方法,将基于现场的观测与基于实验室的测量相结合,和来自地理空间分析的信息。两个研究地点的总共34个随机点被认为是物理,化学,和宏观塑料的生物学特性,以评估它们的相对丰度。人流量较高的地区表现出更多的塑料碎片堆积,与聚丙烯,单独或与聚氨酯和聚苯乙烯结合使用,鉴定为剧毒。碎裂的塑料碎片在两个测试地点都很普遍,然而,未受干扰的Haliday岛展示了大量较少碎片的材料。还强调实施适当的管理制度,以实现无塑料的多样化沿海景观。
