Wind Turbines And Health, Richard Philp Nov 2011

Wind Turbines And Health, Richard Philp

Richard B. Philp

In an effort to reduce the polluting effects of coal-fired electrical generators the Province of Ontario passed the Green Energy Act in 2009. Included in the act were clauses that removed authority from regional governments to control the placement of wind turbine or solar panel 'farms'. In concequence, forests of wind turbines sprang up throughout rural Ontario, angering rural residents and the tourist industry. Despite government claims that low frequency noise (LFN) posed no risks to health, hundreds of complaints quickly surfaced from people experiencing sleep disruption, headache, dizziness, and a host of other neurobehavioural adverse effects. This article reviews …


The "Occupy" Movement: What's It All About?, Richard Philp Dec 2010

The "Occupy" Movement: What's It All About?, Richard Philp

Richard B. Philp

The Occupy Wall Street movement has spread around the world and despite criticism that it lacks clear goals it has raised awareness of many of the societal problems afflicting the middle and working classes including increasing disparity of income between the very rich and the rest of the populace. This paper discusses many of these concerns and speculates on the evolution of the movement.


Human Health And Environmental Hazards Of Farmed Fish, Richard B. Philp Oct 2010

Human Health And Environmental Hazards Of Farmed Fish, Richard B. Philp

Richard B. Philp

Aquaculture, or fish farming, now provides a significant portion of the world's supply of fin-fish for human consumption. Since 1985, the production of farmed fish has nearly quadrupled. Associated problems include levels of persistent organic pollutants and heavy metals as compared to wild-caught fish, enviromnental problems from waste food and excrement, disease hazards for fish and humans and depletion of wild forage fish to produce food pellets for farmed fish. The recent introduction of genetically modified salmon has added another potential hazard for the environment and possible for human health. These and other problems are discussed with recommendations for human …

Richard B. Philp

Bacterial resistance to antibiotics has become a major clinical problem exacerbated by the widespread and sometimes inappropriate use of antibiotics. Reasons for its emergence, mechanisms of resistance, types of resistance and appropriate public behaviour to combat the problem are discussed in language accessable to the general public.


Adverse Health Consequences Following Aerial Spraying With Bacillus Thuringiensis (Var. Kursraki) (Btk) To Control The Gypsy Moth: Flaws In Government Risk Assessments And In Public Health Officials' Attitudes, Richard B. Philp Sep 2009

Adverse Health Consequences Following Aerial Spraying With Bacillus Thuringiensis (Var. Kursraki) (Btk) To Control The Gypsy Moth: Flaws In Government Risk Assessments And In Public Health Officials' Attitudes, Richard B. Philp

Richard B. Philp

The soil bacterium Bacillus thuringiensis is noteworthy for its ability to infect fatally the digestive tract of moths, butterflies and other insects, making it an attractive biological agent to control insects that can damage crops and trees. One subspecies B. thuringiensis (var. kurstaki) is used in commercial preparations such as Foray 48B that can be applied as a spray on the ground or from aircraft. The latter approach is especially appealing as large areas can be sprayed at relatively low cost. The use of such spraying in populated, urban areas often results in reports of illnesses such as nausea, vomiting, …


Reflections On Recycling, Pollution And History Or, How To Beat The High Cost Of Living, Richard B. Philp Oct 2008

Reflections On Recycling, Pollution And History Or, How To Beat The High Cost Of Living, Richard B. Philp

Richard B. Philp

Lessons learned during the Great Depression and World War II may have to be relearned. The three Rs (reduce, reuse and recycle) were essential then to individual and national survival. A fourth R, repair, was practised as well. These lessons, if relearned, will stand us in good stead when dealing with the current economic climate as well as with problems of pollution and global warming.


Autism And Vaccination: The Real Story, Richard B. Philp Apr 2008

Autism And Vaccination: The Real Story, Richard B. Philp

Richard B. Philp

Public perception has linked the onset of signs and symptoms of Autism Spectrum Disorders (ASD) to childhood vacciniation, mainly with the measles-mumps-rubella vavine (MMR). This perception has been reinforced by the very public statements of some celebrities. Numerous clinical studies have failed to show any evidence of such an association and one study that initiallty raised the question has been retracted. This evidence is reviewed and discussed.


Risks Of Herbal Remedies: More Of The Bad And The Ugly, Richard Philp Feb 2007

Risks Of Herbal Remedies: More Of The Bad And The Ugly, Richard Philp

Richard B. Philp

The widespread and increasing use of herbal remedies has increased the risk, and the documentation, of adverse effects. This paper describes some of these that have occurred since 2004. Cases are discussed in which herbal remedies (St. John’s wort, echinacea, grapefruit juice) have altered the metabolism of prescription drugs. Others have interfered with diagnostic laboratory tests (Chan Su, Dan Shen) or caused pseudoaldosteronism due to their (unidentified) content of glycyerrhizin. Aristolochia spp. have caused nephropathy. Hypersensitivity reactions (spice ginger and others), increased sensitivity to ultraviolet therapy (PUVA) (St. John’s wort) have been reported and the consumption of blue cohosh by …


Multiple Chemical Sensitivity: Psychological Or Somatic?, Richard B. Philp Dec 2006

Multiple Chemical Sensitivity: Psychological Or Somatic?, Richard B. Philp

Richard B. Philp

Multiple chemical sensitivity (MCS) is one of a complex group of related disorders that includes fibromyalgia, chronic fatigue syndrome, acute anxiety disorder, and sick building syndrome that share some symptomatology and that are sometimes grouped under the category of idiopathic environmental intolerance or IEIs. In MCS the individual (female in 4 of 5 cases) reacts in an aversive manner to a host of inhaled chemicals (odors) after an initial “sensitizing” exposure. This group is characterized by the absence of any definitive, objective, diagnostic criteria. Because of this these conditions are generally felt to have a predominantly psychological etiology. Nevertheless, there …


Organochlorine Levels In Seawater And Sediment From The Florida Gulf Coast, If Present, Are Low. , Richard B. Philp Nov 2006

Organochlorine Levels In Seawater And Sediment From The Florida Gulf Coast, If Present, Are Low. , Richard B. Philp

Richard B. Philp

Seawater and sediment from the Florida panhandle coast were assayed for a panel of 28 organochlorine insecticides and PCBs. No samples exeeded the detection limits of the analytical technique, which were well below levels reported for other ocean locales. Organochlorine levels in this area of the Gulf must be very low. This does not preclude their biomagnificatioon up the food web.


Organochlorine Levels In Seawater And Sediment From The Florida Gulf Coast, If Present, Are Low., Richard B. Philp Nov 2006

Organochlorine Levels In Seawater And Sediment From The Florida Gulf Coast, If Present, Are Low., Richard B. Philp

Richard B. Philp

Abstract Seawater and bottom sediment from two areas of the Gulf of Mexico near-shore waters along the Florida panhandle, one near Panacea (South of Tallahassee) and the other, St. Joseph Bay, about 100 km to the west, were analyzed for organochlorines (OCs). The first area is contiguous with the open water of Apalachee Bay and receives significant fresh water inflow. The second is a long, narrow bay with a north-facing mouth adjacent to the mainland and little fresh water inflow. Samples were analyzed for a panel of 28 OCs including several insecticides and metabolites as well as hexaxhlorobenzene and total …
