The impact of fertilizers on the uptake of manganese in Cherry Belle radish plants: implications for human health

Abstract

Miracle-Gro Singles, Miracle-Gro Shake and Feed, and Vigoro fertilizers are associated with net loss/enhancement of Mn, up to an order of magnitude when referenced to controls in soil, radish vegetables, and radish leaves; Mn enhancements are a factor of 4 to 65 below the daily required intake for humans (2–5.5 mg/day). Manganese levels were measured by atomic absorption spectrometry (AAS). Control soil, radish vegetables, and radish leaves contained 65 μg/g to 146 μg/g (median = 108), 65 μg/g to 357 μg/g (median = 281), and 185 μg/g to 401 μg/g (median = 323) of Mn, correspondingly. Manganese uptake was ten times greater in radish leaves compared to radish vegetables and enhanced by a factor of 3 in soils. Edible radish leaves/vegetables contain 65 times less than human Mn daily requirements. This equates eating 140 lb/day of radish vegetables/leaves. The fertilizers have a minor impact on Mn accumulation in radish leaves/vegetables. The USDA Nutrient Database for radish (0.69 μg/g of Mn) contradicts this notion as one would need to consume ~ 7 to 18 lb/day of radish to satisfy their daily intake. This study complements investigations showing that fertilizers induce minimal uptake of heavy metals in food; simultaneously, the net loss of Mn amounts observed in some samples of radish leaves and vegetables is analogous to the dilution effect of minerals/nutrients in edibles. Although a deficiency/excess of Mn in one's diet may lead to adverse health effects, background inhalation exposure in general public, occupational, and emergency response settings has a greater influence on one's propensity toward developing adverse health effects related to Mn inhalation exposure.

Quick! Tell the PM: Pumped Hydro is not a “generator”. It’s a $2 – $4b energy chewing “renewables” bandaid.

No more excuses for sloppy, inaccurate language. How can you run a country with falsehoods?

Hydropower is a generator. Pumped Hydro is giant appliance that sucks electricity and gives you back some later. In a system with reliable baseload generators it is superfluous, redundant, and entirely unnecessary. It is an expense we don't have to have, didn't need, and don't want to pay for. It can only make things more expensive than the system we used to have. Not only do we have to pay for the giant infrastructure, every day it operates we also throw away 20 – 30% of the electrons (so to speak) that go through it.

Scott Morrison says it's only $1.4 b from the taxpayer, but the total cost may be $4 billion, and as Judith Sloan says, someone's got to pay — if not through taxes, it will be added to electricity prices. The Snowy Corp may "self fund" it (a deceptively nice way to put it), but they won't be donating the money.

And the Snowy Corp couldn't "self-fund" it from electricity bills if they weren't already so ridiculously high.  If we had enough coal power to keep electricity as inexpensive as it [...]

Vertical variation of bulk and metabolically active prokaryotic community in sediment of a hypereutrophic freshwater lake

Abstract

This study was conducted to acquire novel insight into differences between bulk (16S rDNA) and metabolically active (16S rRNA) prokaryotic communities in the sediment of a hypereutrophic lake (Japan). In the bulk communities, the class Deltaproteobacteria and the order Methanomicrobiales were dominant among bacteria and methanogens. In the metabolically active communities, the class Alphaproteobacteria and the order Methanomicrobiales and the family Methanosaetaceae were frequently found among bacteria and methanogens. Unlike the bulk communities of prokaryotes, the composition of the metabolically active communities varied remarkably vertically, and their diversities greatly decreased in the lower 20 cm of sediment. The metabolically active prokaryotic community in the sediment core was divided into three sections based on their similarity: 0–6 cm (section 1), 9–18 cm (section 2), and 21–42 cm (section 3). This sectional distribution was consistent with the vertical pattern of the sedimentary stable carbon and nitrogen isotope ratios and oxidation–reduction potential in the porewater. These results suggest that vertical disturbance of the sediment may influence the communities and functions of metabolically active prokaryotes in freshwater lake sediments. Overall, our results indicate that rRNA analysis may be more effective than rDNA analysis for evaluation of relationships between actual microbial processes and material cycling in lake sediments.
