The role of human excretion, drinking water, and deposition as a source of heavy metals to municipal sewage was investigated and compared with common levels in sludge for soil application. These sources contributed more than half of the copper (Cu), zinc (Zn), and lead (Pb) content of municipal sewage sludge for soil application, while other sources dominated the fluxes of chromium (Cr) and cadmium (Cd). Drinking water was an important source for Cu and Zn. Deposition contributed about 40% to the Pb flux. Faecal excretion commonly caused less than 10% of the heavy metal load, while urinary excretion was here a negligible heavy metal source.
研究了人类排泄物、饮用水和沉降物作为城市污水中重金属来源的作用，并与用于土壤的污泥中的常见含量进行了比较。这些来源占用于土壤的城市污水污泥中铜（Cu）、锌（Zn）和铅（Pb）含量的一半以上，而其他来源则主导了铬（Cr）和镉（Cd）的通量。饮用水是铜和锌的重要来源。沉降物对铅通量的贡献约为40%。粪便排泄通常导致的重金属负荷不到10%，而尿液排泄在此处是可忽略不计的重金属来源。
