Since ships burn bunker oil, the dirtiest of fuels, that means not just more CO2 but also more "particulate matter", which, according to a controversial paper published in 2007, is already responsible each year for about 60,000 deaths from chest and lung diseases, including cancer.

由于轮船烧的船用油是最低劣的燃料,那就不仅意味着更大量的二氧化碳,更意味着更多的"颗粒物质"将被排放。根据发表于2007年的一份被受争议的研究显示,每年大概有60000人死于由"颗粒物质"引起的胸肺疾病——包括癌症。

Results showed that the topsoil structure of the CK treatment was dense with little porosity developed, and the soil microstructure was sandy granular fabric - granular fabric. In these treatments using chemical fertilizers only, the soil particles did not form soil structure with little porosity, and the soil microstructures in the N, NP or NPK treatment were observed as prophyropectic fabric-fine sand agglomerplasmic fabric, much better than the CK treatment. In those treatments receiving farm manure alone or farm manure plus chemical fertilizers, the quantity of groundmass increased obviously. The soil had a loosen structure, higher porosity, enriched animal and plant residua, iron-manganese nodules and humus, and more micro-aggregates developed. The soil microstructure of the MNPK treatment was pectized-compacted takyric fabric-intertextic fabric, the best microstructure observed among all the treatments.
