<i>Decalobanthus peltatus</i> is a woody vine that commonly utilized in traditional Southeast Asian medicinal preparations. Despite the documented therapeutic uses of D. peltatus, there hardly any information regarding its toxic effects on consumers. In this study, crude leaf extracts (aqueous, methanol, ethyl acetate, and hexane) from <i>D. were prepared evaluated for their embryotoxicity teratogenic effects. Phytochemical screening bioactive compounds plants showed...

Seagrasses are distinct flowering plants which thrive underwater. They part of a complex ecosystem that supports different forms life. Recent studies found out coastal wetlands – mangroves, saltmarshes, and seagrass, far more proficient in sequestering storing carbon than terrestrial ecosystems. Although seagrasses occupy only 0.2% the area oceans, they sequester approximately 15% total storage ocean. Several remote sensing techniques available to map monitor but most them focus on extent...

Abstract Microplastics (< 5mm) have lately been identified in the atmosphere of urban, suburban, and even distant places far from plastic particle areas, suggesting possibility long-distance atmospheric transport microplastics. However, occurrence, fate, transmission, effects these suspended microplastics (SAMPs) are all currently unknown Philippines. This study investigated presence suspected microplastic sixteen cities one municipality Metro Manila, Sampling was conducted using a...

Rivers are essential sources of plastic litter in the marine environment. Recently, Philippines was reported as biggest polluter from riverine sources. However, litter's origin has been less established. In this study, we determined density, composition, and accumulation on riversides Pulot River its tributary Palawan Island, Philippines. We also identified possible litter. Results showed that density highest at river edge during first sampling period. Litter densities for predefined zones...

Abstract Background The Sto. Niño site in Benguet province, Philippines was once a mining area that has now been transformed into an agricultural land. In this area, there significant integration of the three indigenous people (IPs) Ibaloi, Kankanaeys and Kalanguyas with Ilocano community. These IPs safeguard biodiversity traditional knowledge, including medicinal plant use. However, documentation these species their applications not systematic, resultant loss knowledge across generations....

Abstract Mining industries are mandated by law to rehabilitate their mined-out areas. The waste materials, also called as mine tailings left after the extraction of minerals have caused several environmental problems such contamination and alteration soil profiles, pollution waterbodies. Experience in Philippines indicates that mining companies facing major difficulties rehabilitating areas especially raising potential nursery seedlings. Much more outplanting raised seedlings since mortality...
