Imposex is a phenomenon widely associated with environmental exposure to organotin compounds which were quite common components of antifouling paints applied on boats and ship hulls. Here we study the incidence of imposex in neogastropods and its relation with water quality and maritime traffic in the coastal strip of Santa Marta, Colombia. Imposex was determined via specialized indexes and related to the organisms’ size, somatic conditions, variables of water quality and maritime traffic, in a space–time assessment. There was evidence of imposex in five species Plicopurpura patula, Vasula deltoidea, Stramonita haemastoma, S. floridana, and Gemophos auritulus. Purpura patula and Vasula deltoidea species were found in all sampling sites. The results have proved that imposex is highly influenced by the maritime traffic variable, with greater prevalence during the dry season, and with P. patula being more sensitive than V. deltoidea.

哥伦比亚加勒比海圣玛尔塔沿海地区腹足动物物种的致病率

Imposex是与环境接触有机锡化合物广泛相关的一种现象,有机锡化合物是船舶和船体上使用的防污涂料的常见成分。在这里,我们研究了哥伦比亚腹地带的新腹足类动物的暴发性发病率及其与水质和海上交通的关系。Imposex是通过专门的指标确定的,并且在时空评估中与生物体的大小,身体状况,水质变量和海上交通有关。有证据表明,五个种类的百头,虫(Plicopurpura patula)三角迷迭香Vasula deltoidea)Stramonita haemastomaS. floridanaGemophos auritulus有侵害的迹象紫癜在所有采样点都发现了三角葵。结果证明,海上交通量对排烟有很大的影响,旱季的流行率较高,而百叶枯萎病菌三角洲疫病更敏感
