叶绿素缺乏常被用作植物突变研究中敏感的遗传终点。核叶绿素缺陷突变的杂合子的树木的频率被确定为沿着波多黎各西南海岸的红树林种群。杂合子的频率是密切相关的多环芳烃的浓度在底层沉积物和急性和慢性石油污染。虽然流行病学研究很少能证明因果关系，但强相关性肯定与因果关系相容。我们的研究结果表明，石油污染栖息地的生物群可能正在经历更多的突变。
Chlorophyll-deficiency has often been used as a sensitive genetic end-point in plant mutation research. The frequency of trees heterozygous for nuclear chlorophyll-deficient mutations was determined for mangrove populations growing along the southwest coast of Puerto Rico. The frequency of heterozygotes was strongly correlated with the concentration of polycyclic aromatic hydrocarbons in the underlying sediment and with both acute and chronic petroleum pollution. Although epidemiological studies can seldom prove causation, a strong correlation is certainly compatible with a cause-effect relationship. Our results suggest that the biota of oil-polluted habitats may be experiencing increased mutation.
