We studied the bioaccumulation of metals and PAHs, the pathological conditions, regressive phenomena and pathogens in wild Mytilus galloprovincialis taken along the North Pier facing the former second Italian largest steelworks of Bagnoli. There was no Cd and Pb bioaccumulation with respect to the EU role 221/2002. Metal shell index decreased as follows: Pb > Ni > Zn > Cu and correlates with the pollution state. The level of BaP was up to thirtysixfold higher the EU rule 835/2011. The sum of 4 hydrocarbons, PAH4, were up to seventeen-fold the rule. PAH levels increased toward the coast. Prevalence values of tissue necrosis and inflammatory lesions were between 50 and 100%. In May animals showed lesion like granulocytomas and inflammatory capsules. Signs of atresia, necrotic oocytes and diffused cases of hermaphroditism were detected. An appropriate localization of farming to avoid contamination from sediment turbulence and risks for consumer health is needed.
我们研究了沿那不勒斯湾北防波堤野生贻贝的金属和多环芳烃的生物积累、病理状况、退行现象和病原体，这些贻贝取自曾拥有意大利第二大钢铁厂的巴尼奥利前址。就欧盟指令 221/2002 而言，贻贝体内未积累 Cd 和 Pb。金属外壳指数依次降低：Pb>Ni>Zn>Cu，且与污染状况相关。BaP 水平比欧盟指令 835/2011 规定的上限高 36 倍。4 种碳氢化合物（PAH4）的总和比规定值高 17 倍。多环芳烃水平沿海岸增加。组织坏死和炎症病变的流行率值在 50%到 100%之间。5 月，动物出现类似于粒细胞瘤和炎症囊的病变。发现闭锁、坏死卵母细胞和弥漫性雌雄同体的情况。需要对养殖进行适当的定位，以避免沉积物紊流的污染和对消费者健康的风险。
