有一组结构与双酚a （BPA）相似的化合物，即双酚（BPA），其中一些化合物被认为能够部分取代BPA。为了评价各种bp在水生环境中的生物降解性；双酚a、双（4-羟基苯基）甲烷（BPF）、双（4-羟基苯基）乙烷（BPE）、2,2-双（4-羟基-3-甲基苯基）丁烷（BPB）、2,2-双（4-羟基-3-甲基苯基）丙烷（BPP）、双（4-羟基苯基）砜（BPS）、硫代二酚（TDP）和4,4'-二羟基苯甲酮（HBP）；在好氧和厌氧条件下进行生物降解试验。在好氧降解试验中，采用了一种采用多个河流水样的河流消亡法，而在密封的缺氧瓶中采用了池塘沉积物进行厌氧降解试验。总的来说，所检测的bp可以根据其在好氧条件下的生物降解性进行排名；Bpf, HBP >> > BPP >> BPB > TDP >> bps。另一方面，厌氧生物降解的趋势是；BPF > HBP > bps, bpa, TDP > bpe > bpb。从生物可降解性的角度来看，双酚pf似乎比双酚a更环保，因此可能是替代双酚a降低环境风险的候选物质。
There is a group of compounds structurally similar to bisphenol-A (BPA), namely bisphenols (BPs), and some of them are considered to be able to partially replace BPA. In order to assess their biodegradability in the aquatic environment, a variety of BPs; BPA, bis(4-hydroxyphenyl) methane (BPF), bis(4-hydroxyphenyl)ethane (BPE), 2,2-bis(4-hydroxy-phenyl) butane (BPB), 2,2-bis(4-hydroxy-3-methyl phenyl) propane (BPP), bis(4-hydroxyphenyl)sulfone (BPS), thiodiphenol (TDP) and 4,4'-dihydroxybenzophenone (HBP); were subjected to biodegradation tests under both aerobic and anaerobic conditions. For the aerobic degradation test, a kind of river-die-away method using several river water samples was used, while pond sediments were used for the anaerobic degradation tests in sealed anoxic bottles. As a whole, the examined BPs could be ranked by their biodegradability under aerobic conditions; BPF, HBP >> BPA > BPP > BIDE > BPB > TDP >> BPS. On the other hand, the tendency for the anaerobic biodegradability was; BPF > HBP > BPS, BPA, TDP > BPE > BPB. From the viewpoint of biodegradability, BPF seems to be more environmentally-friendly than BPA and, therefore, may be a candidate to replace BPA for reducing the environmental risks.
