Perilous effects of polystyrene fragments on male reproductive system and tenable directives of remediation.

Abstract

Indiscriminate use of polystyrene (PS) plastics has posed a major problem for its disposal and recycling on one hand, while on the other hand, fragmentation of these into micro/nano compounds threatens the living world by its toxic effect. The small sized particles can be present in any ecosystem and pose threat to the living world there. The unique properties of these small-scale fragments allow them to cross the barriers of human bodies and affect the vital organ system, altering the normal physiological parameters. Male reproductive system is highly affected by these micro/nanoplastics which leads to infertility and other physiological complications. Smaller number of literatures has been reported in this field in comparison to female reproductive system. The signaling mechanism of polystyrene micro/nanoplastics (PSMP/NPs) have been discussed in this review. There are lacunae in this regard which have been addressed very specifically. Many reports of biodegradation processes have been put forward, but not without any additional hazards. This review puts together the existing literature on the effect of PSMP/NPs on mammalian male reproductive system, throws light on the possible bioremediation methods using microorganisms, and highlights the unattended areas of study so that the future research finds a way for these problematic aspects.
