Rudi,
I don't know what, if anything, this might do for counteracting toxins, but myself, Luella and others have had wonderful results getting rid of difficult infections that included lingering chest congestion that normal remedies could not conquer by using 5 parts colloidal silver to 1 part Dr. Christopher's Lobelia extract and taking a wonderful Chinese formula called ClearLungs Extra Strength. That combo seems to really knock out bugs and is wonderful for clearing gunk out of the lungs as well as healing them. Check out a list of the ingredients of ClearLungs and you will see why it could be so effective for lung issues:
Hoelen - Balances fluids and supports healthy respiratory membranes.
Dong Quai - Tonic and blood builder.
Ophiopogon - Balances fluids, supports healthy respiratory membranes.
Scute - Supports healthy tissue.
Platycodon - Supports a healthy immune system.
Citrus - Supports the lungs and circulatory system.
Morus Root - Supports normal tissue repair.
Fritillary - Supports normal tissue repair.
Chinese Asparagus root - Supports proper lung function.
Almonds - Supports proper fluid balance.
Gardenia - Supports proper lung and liver function.
Schizandra - Helps support normal mucus secretion.
Licorice - Supports the adrenal glands.
When I was living down in Utopia Texas with my good friend Ben Taylor (the owner of CZ sponsor Utopia Silver Supplements) we had a few rounds of some kind of bug hit us and it was pure Hades to get rid of - it just lingered on an on and seemed to get passed around the office. Normally, colloidal silver and perhaps another item or two would get rid of a cold and cough, but not in that case. Those of us who used the above combination were rid of it in a matter of days, whereas those who only took colloidal silver or relied on other methods, including mainstream meds, took two weeks or longer to get mostly over it and often had it return. It might be noteworthy to observe that every single time that dang bug came around it was right after we had observed very heavy chemtrails followed by a rain.
Then, when Luella went to California to see her children the smogs and other foreign items in the air led to an asthma attack that put her in the hospital (and she had not had asthma for decades). The hospital was hardly able to help her and said that she was developing pneumonia. Only after she was released and ditched her antibiotics and inhalers and used the colloidal silver, lobelia and ClearLungs did she get markedly better, though it took getting out of California to finally get over the asthma once and for all - and it has not returned since.
Not knowing what all might be blowing and washing in from the oil, gas and dispersents, if it were me I would be looking at regular cleanses and try to include items like cilantro, chlorella and parsley. Echinacea might be a good add too.
Another thing that would be well worth considering would be investing in plenty of houseplants. Several species really do a wonderful job of eliminating household toxins in the air. See:

I'm not trying to shill for Utopia Silver, but I will note that they carry all of the items save Echinacea and they have a discount code for CZ members of LR001 to get 15% off virtually all items (unless they are on sale at the time).
As a side note, I fear that the Gulf oil volcano will be an unprecedented environmental disaster which will not be overcome in our lifetime or even that of our children and grandchildren. Sadly, and I guess selfishly, Luella and I had planned to take a trip to Destin next summer to enjoy the lovely white sand beaches and clear blue water. I am afraid that is something we will never be able to do now.
I hope that helps.
Watercress is a great antihistamine and contains oils that will help fight any possible infection from damage or immune suppression.
If the mucous gets yellow-green or blackish brown this can indicate an infection. If it turns in to an infection let me know and I can give you a simple recipe to clear up pneumonia or bronchitis in a few days.
I also recommend chaparral, which is a powerful blood cleanser and it supports the adrenals to reduce chemical sensitivities.
If you have an ozone unit you can run in the house you should do this. Ozone destroys most hydrocarbons through oxidation breaking them down in to carbon dioxide, water and oxygen.
