英文摘要 | In past decades, large amounts of N fertilizers have been applied in agricultural production of China. N fertilizer has not only underpinned food production but also led to great concerns about negative environmental impacts. We used a life cycle assessment (LCA) approach to assess nitrogen fertilizer induced potential human health risk (HHR) and human capital loss (HCL) of rice, wheat and maize production systems. We found that the HHR of rice, wheat and maize was 633004, 264105 and 418644 DALY/yr, respectively. The rice production system caused the highest potential risk while the wheat production system the lowest. Fine particulate matter formation (FPMF) was the most serious health risk index, and accounted for nearly 87% of HHR. Sown area and crop type both play an important role in HHR. The potential loss of human capital caused by rice, wheat and maize production are 37.5, 15.6 and 24.8 billion RMB/yr, respectively. The total HCL accounted for about 5.9% of the Chinese grain yield value in 2017. We constructed 3 scenarios to evaluate the potential for reduction of human health risk. In scenario A, reducing N fertilizer rates to an appropriate level, the HHR decreased by about 23%, while in scenario B, enhancing nitrogen use efficiency and production technology, decreased HHR by about 22%. Furthermore, when we combined both scenario A and B, the HHR was reduced by as much as 37%. Improving fertilizer management practices in grain production in China has a great potential to reduce adverse impacts on human health, and more attention should also be paid to the impacts of air pollutant emissions from agricultural production on human health.
