除Cu线性拟合误差为15%，其他三种物质释放通量拟合误差均在10%以内

Except for Cu, which has a linear fitting error of 15%, the fitting errors of the other three substances' emission fluxes are all within 10%. However, when the law is verified at four outdoor locations, it is found that there is a point (S2) heavy metal emission flux. This rule is not met, and the error of the measured and theoretical values ​​of the other three points is within 30%.

In addition to the Cu linear fit error of 15%, the other three substance release vector fit error is within 10%, however, when the law is verified at four points outdoors, it is found that one point (S2) heavy metal release communication does not meet this law, and the other three point measured values and theoretical value errors are within 30%.

Except the linear fitting error of Cu is 15%, the fitting error of the other three substances release fluxes is within 10%. However, when the rule is verified at four outdoor sites, it is found that the heavy metal release flux of one point (S2) does not meet this rule, and the error between the measured and theoretical values of the other three points is within 30%.<br>
