【摘要】 用定时多点取样和分光光度测定法,对茂名市近海养殖区海水挥发酚和氰化物含量等指标进行了检测。测定结果表明;各水样中挥发酚含量都在0.014～0.026mg/L之间,而氰化物含量在0.00780 ～0.00873mg/L之间,分别接近国家规定的四级标准和三级标准,两者都大大超出了国家规定的优良海水水质标准,表明茂名市近海水域水质环境污染较为严重,应当引起高度重视。更多还原

【Abstract】 According to the present situation of disease problems in seawater fishery of Maoming onshore, we monitored the contents of volatilizable phenol and cyanide in seawater with the method of timing sampling analysis at different places and spectrophotometer menstruation. The result shows as following: In all places, the volatilizable phenol content is between 0.014 - 0.026 mg/L for each sample, which reached basically the grade 4 standard of national stipulation, and cyanide between 0.00780 - 0.00873 mg/L, basically reached the grade 3 of national stipulation of the sea-water. All these especially tell us that the harmful materials in seawater in some places have seriously affected the development of fishery for Maoming onshore. The water qualities should be kept to monitor on route plan.更多还原
