Abstract
Coastal environments are subject to trace metal pollution via a combination of industry and urbanised sources. The pollutants accumulate within surface sediments, especially in the quieter backwaters of estuaries. An environmental assessment of the Port Hacking estuary, southern Sydney, Australia, was undertaken using 233 surface samples. Trace metal concentrations (Ni, Cr, Cu, Zn, Pb, and As) in these samples indicated that most elements in Port Hacking were below the relevant ANZECC/ARMCANZ guideline low trigger value (ISQG-low), but a few sites exceeded this value. The low trace metal concentrations are mainly because the catchment areas have limited urban development and few discharge points. In contrast, one site in Gunnamatta Bay has Zn and Cu concentrations that exceeded the high trigger value (ISQG-high), due to moored vessels, boatyards, and stormwater outlets in this vicinity. Port Hacking is considered to be relatively unpolluted and healthy when compared with ot
4,300 Years of Bat Poop From The Depths of a Jamaican Cave Have Revealed Earth s Past
14 APRIL 2021
You may not give a pile of bat poop gathered over 4,300 years a second look – but to a group of scientists, it s provided an intriguing insight into how bat diets and therefore climate conditions have shifted over thousands of years.
Taller than the average man (2 meters or 6-and-a-half feet), the pile of poop (also known as guano) records history in clear layers, much like sediments under a lake.
By analyzing the layers back through time, the scientists have been able to figure out changes in the diets of the bats that have been inhabiting this cave for millennia.
Renforth Resources Inc.: New Gold Zone at Parbec Discovered by Renforth in Pontiac Sediments
PICKERING, ON / ACCESSWIRE / March 17, 2021 / Renforth Resources Inc. (CSE:RFR)(OTCQB:RFHRF)(FSE:9RR) ( Renforth or the Company ) is pleased to announce the discovery of a new gold mineralization zone at Parbec, located in the Pontiac sediments, south of the Cadillac Break, outside of the existing resource model.
PAR-20-105 offered the following highlights in the top of the hole. The sample from 83.4 to 84.9m is unconstrained, meaning that there are no samples on either side of the highlight value of 5.34 g/t Au. In the future Renforth will revisit this core and select additional samples in order to confirm the extent of mineralization.
