Microplastics are ubiquitous in our environment, resulting animal exposure and consumption via various means, such as food, water, air. Animals that consume microplastics may undergo physiological changes immunotoxicity mitochondrial dysfunction. In this study, I measured the transcriptomic responses to microplastic tropical house cricket species Gryllodes sigillatus. Using RNA-Sequencing at tissue-specific levels (midgut, hindgut, fat body ovaries), provide comprehensive insight on how impact specific organ systems. Here, used assembler ‘Trinity’ generate a de novo transcriptome, there is currently no genome established for G. sigillatus date. This transcriptome was then infer differential gene expression due consumption. Ingestion of elicited unique depending tissue focus, induced pathways related metabolism, immunity, cancer, stress, survival.

Insects, being among the most diverse and abundant organisms in terrestrial ecosystems, are inevitably exposed to ubiquitous micro- nanoplastic contaminants. Although studies on impact of these contaminants insects gradually emerging, they remain limited scope. In this study, we investigated biological traits (including foraging behavior, food assumption, digging ability, body weight survival) Japanese carpenter ant, Camponotus japonicus, response exposure polystyrene (PS-M/NP) solutions containing three particle sizes (0.05, 1 50 μm) four concentrations (0.1, 1, 10 mg/mL). The results showed that worker ants exhibited significant preference consumption for non-contaminated multiple-choice experiments, indicating C. japonicus can differentiate avoid feeding PS-M/NP-contaminated solutions. Meanwhile, PS-M/NPs significantly reduced ability no-choice with smallest size (0.05 highest concentration (50 mg/mL) resulting longest pre-foraging period, lowest percentage licking amount consumption. addition, sand removed by ants, survival a dramatic decline decrease size, increase prolonged time study confirm have an adverse effect time-dependent manner, small high longer key factors decreasing behavior insect.

The term microplastics (MPs) describes a heterogeneous mixture of particles that can vary in size, color, and shape. Once released into the environment, MPs have various toxicological physical effects on wildlife. Song Thrush (Turdus philomelos) is migratory species, staying Italy late autumn winter. aim this study to assess, quantify, characterize presence Thrushes hunted Apulia region Italy. birds (n = 360) were Bari countryside donated for research purposes by hunters. classified relation their shape fibers, films, fragments, pellets; then, they divided according color length was measured. Nikon image analysis software applied litter size measurements. Of total 360 birds, detected stomachs 129 shot December 128 January. majority ingested fibers observed all contaminated birds. Film fragments every specimen. Among found, 31.75% red, 30.13% black, 25.91% blue, while other colors less represented. This provides first bioaccumulation wintering region, high contamination thrushes confirmed ubiquity terrestrial ecosystems.

Microplastics (MPs) are widely detected in urban drinking water systems. However, the presence and characteristics of MPs mountainous systems with independent simple filtration facilities have been overlooked. In this study, we revealed ubiquity demonstrated that their concentrations increased along pipeline length Bainitan Village, Tiantai County, China. The facility village did not effectively remove most MPs. Polyethylene, polyurethane, polyethylene terephthalate were dominant polymers samples (72.32% total), while polyvinylchloride, prevalent sediment (74.00% total) reservoir. Long fragments predominant shape all samples, majority being smaller than 100 μm. estimated daily intake through ingestion was highest infants (2.14-31.26 MPs/kg bw/day), compared to children (1.41-20.67 bw/day) adults (1.05-15.35 highlighting vulnerability. This emphasizes need for advanced treatment regions. It also underscores necessity government attention improve safety remote areas. Our research will contribute valuable baseline data further on MP exposure, particularly communities.
